There are many kinds of electric hammer bits, and we use different bits to drill different things. Of course, drill bits made of different materials are different. If you are worried about buying the wrong one, you should carefully study the specifications and models of the electric hammer bit. Only in this way can we know whether we need a drill. Let's take a look at the specifications and models of the electric hammer drill.
Specification of electric hammer bit: 6mm, 8mmx110mm; 8 MMX 160mm； 8mm,10mm,12mm x 2 10/0mm,10mm,12mm, 20mm x 450.
The main body of cemented carbide electric hammer drill is made of high-quality alloy steel, and the cutter head is welded with cemented carbide. Suitable for drilling holes in hard building materials such as concrete and bricks. In the construction and installation industry, it is a multifunctional and efficient punching tool.
The specifications of electric hammer drill set are: 5* 1 10mm, 6 *10mm, 6* 160mm, 8 *10mm,10mm.
Electric hammer bit: round shank or square shank: 6mm 8mm10mm12mm14mm16mm-28mm.
Wall drill: length 350 mm16 mm18 mm 20 mm 22 mm 25 mm 28 mm.
Characteristics of electric hammer bit
1, good damping system: it can make the operator hold it comfortably and relieve fatigue.
Implementation mode: through the "vibration control system"; Increase the grip comfort through the soft rubber handle;
2. Accurate speed control switch: the touch switch has a low speed, which can help the machine to trip out smoothly (for example, tripping out on smooth surfaces such as ceramic tiles, which can not only prevent the bit from slipping, but also prevent the hole from breaking. High speed can be used during normal operation to ensure work efficiency.
3. Stable and reliable safety clutch: Also known as torque limiting clutch, it is a kind of safety protection for users to avoid the transmission of large torque reaction force caused by the bit sticking to the user during use. This feature can also prevent the gear device and the motor from stopping rotating.
4. Comprehensive motor protection device: In use, it is inevitable that granular hard objects will enter the interior of the machine (especially when the machine operates upward, such as drilling on the top of the wall). If the motor is not protected to a certain extent, it will be easily broken or scratched by hard objects during high-speed rotation, which will eventually lead to motor failure.
5. Positive and negative rotation function: it can make the application of electric hammer more extensive, and its realization form is mainly realized by switching or adjusting the position of carbon brush. Usually, big-name tools will adjust the position of carbon brush (rotating brush handle), which is convenient to operate, effectively restrain sparks and protect commutator, and prolong the service life of motor.
What are the precautions for the use of electric hammer bits?
We should be more careful not to hurt ourselves when using the electric hammer bit, and we must know what we should and should not do, so it is necessary for us to know what to pay attention to when using the electric hammer bit. Only in this way can we pay attention to these problems when using, but people don't realize them here, so Bian Xiao introduces the precautions in the use of electric hammer drill here. What are the precautions for the use of electric hammer bits?
1. Confirm whether the power supply connected on site is consistent with the nameplate of the electric hammer. Whether the leakage protector is connected. The drill bit and holder should be adjusted and installed correctly.
2. When drilling walls, ceilings and floors with an electric hammer, first confirm whether there are buried cables or pipes. When working at height, pay full attention to the safety of objects and pedestrians below, and set warning signs when necessary.
3. Confirm whether the switch on the electric hammer is turned off. If the power switch is turned on, when the plug is inserted into the power socket, the power tool will suddenly rotate, which may cause personal injury. If the workplace is far away from the power supply and it is necessary to extend the cable, an extension cable with sufficient capacity and qualified installation should be used. If the extended cable passes through the pedestrian passage, it should be raised or measures should be taken to prevent the cable from being squeezed and damaged.
